Everclear

Bruce Ediger

Summer 2021 I bought a Stirling Cycle engine kit. This is a type of heat engine, and in the case of the kit I assembled, the heat came from a small alcohol lamp.

I went to the local drive-thru strip mall liquor store to buy some Everclear.

Wireless Charging Detector

I dropped my cell phone and cracked the screen, so I got a Google Pixel 6 and a wireless charging stand. I ended up looking up the “Qi” standard for these chargers. It seemed like the coils used to transfer energy weren’t particularly exotic in size, shape, material or manufacture, so I decided to try to receive some energy from the charging stand.

I’ve since revised this contraption.
